Here's a thought...do you have your heart set on a late model car?
If not, there are tons of '60's and '70's era Alfas or Fiats available. You could get in relatively cheaply, they're pretty straightforward mechanically so you can do your own repairs, and c'mon....what's cooler than an old Italian drop-top?
You'd have something very few people have now days, they're great looking, you can flog 'em around a track too, and you'd be preserving a piece of automotive history.
Just another thought for you to toss in with the rest.
